This feature is intended to prompt to remove any Release Candidate version from 2007.This feature will prompt to upgrade any E-Prime 2.0 version in 2008 or later.This feature does not handle the E-Prime 2.0 BETA, which requires manual uninstall through the Add/Remove Programs applet.Because of the complexities of the installation process, if errors or other difficulties occur while installing, then manually remove E-Prime 2.0 prior to installing the newer version of E-Prime 2.0.To assist with debugging upgrade issues, optionally use Windows Installer logging switches and send the log files to PST Tech Support.To enable logging, use the command line switch:msiexec /lvoicewarmupx "C:\install.log" "D:\E-Prime 2.0.msi"Where C:\Install.log is the path to where to log the installation and D:\E-Prime 2.0.msi is the path to the E-Prime folder on your E-Prime 2.0 CD.For minimal installations, download the .exe and extract it to a temporary folder using a tool such as WinZip.
